do you have a PFC? if so the pfc has a safety function that is warning you of something, check your manual if you have one. if you dont have a PFC then it might be a short.. also are is the heat light or exhaust overheat light, there is a difference and you can turn one on and off with a switch.

That lamp is turned on by an over heated cat. I had my sensor removed (because I dont have a cat anymore) but I know that It turns on when you have a lean condition, but also if you have too much fuel being dumped into the exhaust.
2 things - Check for leaky injectors, and check your tune with a wideband O2 as you may have a lean spot in yor tune.
Good luck,

My injectors were originally set to come in at 1200rpm on the PFC, but often when the car dropped rpm to idle it would stall. I was advised by JD to alter it to 1450 (which I did). Could this be the problem?
The setting changed was the rev/idle
F/C A.E 1450
F/C E/C 1450
F/C A/C 1450
IDLE A.E 900
IDLE E/L 900
IDLE A/C 1000
Would these settings effect it?

I forget what warning this applies to but the PFC uses this light for a different warning. I thought it was excessive knock but it's been a while since I've looked through PFC docs. Since US cars have the Exhaust Overheat by the fog light/defroster switches and not in the dash that function does not work for us. I would look in the PFC forum on here for more info.

I have removed the cat and sensor as well but now the exhaust heat light is on all the time. Is there a switch I can access in my PFC (with datalogit) to turn it off?
Also will this light trip a limp mode in the PFC?
It is running pig rich at the moment at thought it might be related.
Thanks.
